"I knew very little about personality type prior to this course... At first it seemed overwhelming, but as the class continued, the instructor Bob McAlpine, made it all make sense. He is wonderful at what he does and this class is well worth the investment. I am looking forward to using type instruments to better understand people and assist them in communicating with others, either on a professional level or in a group setting. It appears to be a wonderful instrument with so many possibilities."
